FLUID-EJECTOR.

SPECIFICATION forming part of Letters Patent No. 372,024, dated October25, 1887.

Application led March 5. 1887. Serial No. 229,42. (No model.)

To all whom, it may concerns `pipe, but below the ejector.

Be it known that we, CLARENCE, M. KEMP 'and CHARLEs E. KEMP, citizens ofthe United States, residing at Baltimo-re, in the State of Maryland,have invented certain new and useful Improvements in Fluid-Ejectors; andwe do hereby declare the following -to ybe a full, clear, and exactdescription of the invention, such as will'enable others skilled in theart to which it appertains to make and use the same.

Cur invention relates to that class of Huidejectors illustrated anddescribed in Letters Patent No. 356,647, granted to us January 25, 1887,in which a valve is located inthe supply-pipe leading from a main, andthe valve-operating mechanism is given a quick movement to produce asudden pressure through the ejector, and thus give an effectivemomentumto the static water.

' Our improvements consistinchanges in the form of the valve andconnectingparts,where byit can be located and operated in the press"ure-pipe without being inimmediate connection with the ejector and setin any direction, vertically, horizontally, or at an angle,withoutchanging its parts or operation. It is illustrated n the accompanyingdrawings, in

,which- Figure l is a side view, partlyin section, in position in a wellor tank; Fig. 2, aview when used in a horizontal position; Fig. 3, adetail partly in section, and Figs. 4, 5, and 6 details.

In the drawings, A is awell or other receptacle from whichwater or otherliquid is to be ejected; B, a pressure pipe; C, an ejector, and D thedischarge-pipe.

In the form illustrated in the drawings, the valve and valve mechanismare located on avertical line with the ejector and discharge The valveportion is composed of an outside casing, E, a central chamber, F, and alower water-chamber, G. yThe pressure-pipe is connected to thiswater-chamber. To one end of the valvecasing is connected the ejector C,which at its opposite end is connected to the discharge- 1 e. p LLI is avalve on a stem, I. It is located in the water-chamber G, andcloses thepassage m between that chamber and the chamber F. A N is a gnide,whichmay be cast on the valveseat o, or otherwise'connected thenewith. The

stem I is passed through this guide, and is directed and steadiedthereby so as to hold the valve squarely to the under side of the seato. The guide is channeled to permit the liquid to pass up around it. Thevalve-stem is provided with an upper collar, p, and a lower collar, 19.

R is a spindle, provided with a flange, r, to which is attached acrank-arm, r. It is passed through a boss, r2, on the valve casingcrankextends between the collars p p. The crank acts as a lever, ashereinafter described, and a cam or other suitable mechanism may besubstituted therefor. The boss r2 is screwthreaded internally, intowhich is inserted a screw cap, S, through which the spindle R is passed.The inner end of the cap, when screwed into the boss, forms a seat forthe iange 1' of the spindle and also a tight joint at that point. Acollar, s', on the cap its snugly against the boss. The spindle R turnsin cap S and boss r, and it is cut out alittle at its central portion,r3, in order that it may turn thehmore freely.

L is a lever, keyed tothe end of spindle R and provided with a float, W.Instead of a cap, S, alug can be used, bored for the spindle The with anopening and plug on opposite side of 8o casing for the introduction ofspindle.

The ejector C andthe valve-casing, as before suggested, may be placedvertically,lhori zontally, or at an angle, or the valve-casing may beplaced in one directionand the ejector in another.

In Fig. 2 the valve-and casing are shown in a horizontal position andthe ejector and discharge-pipe at a right angle therewith.

The operation of the apparatus is as follows: Before the valve isoperated the water or other liquid from the pressure-pipe fills thechamber G, thus increasing the head-pressure,which acts against thevalve H, aiding to hold the valve against its seat. As the water orliquid in the receptacle or cellar rises above or surrounds the ejector,it flows therein through ports c c?, and as it continues to rise itlifts the float and lever until the spindle R is made to revolve, whichmovement actuates the crank or cam, turning it against the lower collar,p', of the valve-stem and forcing the valve from its seat. At thatmoment the water from the pressure-pipe and water-chamber rushes inabove the valve, giving to the valve a quicker throw, continues onthrough the central chamber, giving to the water in the ejector suchmomentum as to create a vacuum, whereby the water in well A isdischarged through discharge-pipe D, until the water in well A hassubsided, and the float and lever, falling therewith, the crank-lever ris carried against the upper collar, p, partially closing the valve,when the rushing water from chamber G to E through ortice m carries thevalve the balance of its throw and seats it.

The operation is automatic and the receptacle can be almost oraltogether drained, according to the situation of the valve-easing andejector. y

lt will be seen by our improvements that little or no packing isrequired, the valve when closed being Iliade watertight not only bytheweight of the float, but bythe pressure of the water-the greater thepressure the more tightly is it held closed. As the cranklever workingthe valve is within the valve` chamber and acts directly upon the valveand is located 011 the discharge side thereof, the parts are free fromfriction and respond quickly and freely to the action of the lloat-leverand the water-pressure. By the water-pressure against the rim or flangeon the spindle a tightjoint is also formed at the pointof connection ofscrew-cap and spindle head, thus avoiding the use of packing there. Byour improvements, also, the ejector need not be immediately connectedwith valve, but may be placed at any desired distance from the valve,and two or more ejcctors may be employed, if desired, and set in anydesired po- Sition.

XVhat we claim isl. ln a device for ejectiug liqhids, the combinationofthe pressure-pipe, discharge-pipe, and ejector with a valve receivingmotion from a loat and lever, with connections extending into interiorof valve-frame and there engaging with valve.

2. The combination of ejector and pressure and discharge pipes with avalve receiving motion from a lloat and lever, with connectionsextending into interior of valve-frame and there engaging with valve ondischarge side of saine.

3. In combination with the valve and its connections, the spindle orlever provided with a flanged head or collar and plaeedwithin thevalve-casing, and forming a seat or joint against the inner part ofcasing or cap, and a float lever for operating the said spindle.

4. The combination ot' the pressure-pipe, discharge pipe, and ejectorwith a valve located in the pressure-pipe, receiving its movementthrough a float or diaphragm, and connections making a turning orrevolving movement.

5. The combination of a prcssure-pipe with a ioat and connections, avalve moved positively a certain distance by means ofthe float andconnections, and the balance of its throw quickly by the fluid-pressureand the detachable ejector, whereby the ejector can be placed at anydesired point on the pressurepipe away from the valve, substantially asdescribed.

6. In combination with the valve-chamber and fluid-chamber, the valvemechanism composed of the valve, valve-stein, guide-plate, .and collarson the valvestem, and the spindleearrying the crank-arm to operatebetween Said collars, substantially as and lfor thc purpose described.

In testimony whereof we affix our signatures in presence ol' twowitnesses.
